A tiorncy Patented Sept. 13, 1932 UNITED STATES ALLAN RINNE, or can, mrniinsorn Application filed December 7,1929, Serial No. (112,535.

This invention appertains to new and useful improvements in accelerators, and it is an improvement over my co-pending application, Serial No. 407,147, filed November 14, 1929 and patented June 2, 1931, No. 1,807,706.

The principal object of this invention is to provide an accelerator control of marked simplicity, yet of extreme durability and positive acting in operation.

Another important object of the invention is to provide an accelerator which can be 0011', trolled without removing the hands from the steering wheel.

These and numerous other important ob jects and advantages of the invention will become more apparent to the reader after considering the invention as described and claimed in hereinafter.

In the drawings Figure 1 represents a fragmentary sectional view through the forward portion of an automobile, showing in side elevation the improved steering wheel and the connection between the steering wheel and the throttle w 7 g V v 7 novel steering wheel-is shown, and this is substantially as ShQWn and described-in my be- -fore mentioned patent. Briefly, thissteering wheel structure comprises spokes. 24 radiatvalve of the carburetor.

Fig. 2 is a top plan view of the improved steering wheel.

Fig. 3 represents a fragmentary top plan view of the steering wheel hub showing the cap thereof removed.

Fig. 4 is a fragmentary sectional view taken substantially on the line 4'4= of Fig. 2.

Fig. 5 is a fragmentary side elevational view.

Fig. 6 represents a fragmentary vertical sectional view taken substantially on the line 6-6 of Fig. 3.

Fig. 7 is a sectional view taken substantially on the line 7-7'of Fig. 5.

Referring to the drawings wherein like numerals designate like parts, it can be seen in Fig. 1, that numeral 5 generally refers to the internal combustion engine and numeral 6 denotes the usual carburetor. The steering shaft housing is designated by numeral 7 and through this is disposed the usual hollow steering shaft 8 (see Fig. 6). 7

At the upper end of the housing 7, there is a hub structure 9 which has a skirt 10 for engaging over the upper end of the housing 7.

.The upper. end .of the stem. 19 1s secured to 2'5 abovethe, wheel. Sleeves 26are. arranged .on the rim between the spokesand preferably number four. a

This hub 9' iskeyed to the shank: 11 of the shaft Sas at 12, and this shank 11 is threaded at its upper end forengagement within the nut 13, which-nut is disposed within the sre cess 14 at the top side of the hub 9. r EQ v The hub 9 is secured to the bottom 'of the W circular shell 15 which has arfemovable cover plate. 16, capable *being se curedutomthe shell 15 by screws'17. Mounted, uponthe bottom. of the shell :15 5,9 are the arcuate=sha ped cams 18 ,18,.arranged in a circular disposition substantially "con centric with-respect to the longitudinal axis of the shaft 8. c 1. f I E.

jAs is clearly shown in Fig. 6,.a-stem '19 is rotatably. and slidalolyv disposed througha bore 20 in the shank 11,-and the lower end of this stem.1 9 is pivotally connected as; at v2 1 to the upper end of the connecting rod t e n rm i e por n ofia ocker' rm23, the. end: portions of which, are engageable with the cams .l8=-18. 1

s In Figs. 2 and 4, the construction of. the

ing fronrthe hub 9 and connected to the rim Qerta-inof the sleeves 26 vhavetheir opposediends connected by rods 27. As is clearlyshown" in Fig. 2, a pair of these rods, one at a pair of diametrically opposite sides on the wheel, are provided with bell cranks 28, connected at their free ends to rods 29 through the agency of pivotal links 30. These rods 29 extend through certain of the spokes 2 g which are hollow and connect from the rocker arms 23. Thus in place of the rheostat shown and described in my patent, mechanical means is provided for operating the accelerator. 3 This is accomplished by connecting the lower end of the rod 22, to the rocker arm 31, which arm is supported by the bracket 32 at the lower end of the steering shaft housing 7. As is clearly shown in Fig. 7, the rod 22 is equipped with a ball 33 which is engaged within the sectional socket 34 provided at one end of the rocker arm 31.

As is clearly shown in Fig. 5, this rocker arm is pivoted to the bracket 32 as at 35. The opposite end of the rocker arm has an elongated rod 36 pivotally secured thereto at its lower end, while its upper end is pivotally connected to the lever 37, which is in turn connected to the throttle valve of the carburetor 6.

It will thus be seen that when a twisting 1 motion is imparted to thesleeve 26, the bell crank 28 will be operated so as toswing the rocker arm23n The arm riding on the cams 18,18 will 7 elevate the connecting rod 22 and this in turn will exert'a pull on the rocker arm 31. Thus motion is imparted to the rod 36, which in turn actuates the throttle valve of the carburetor.

A device of this simple nature can be manufactured at a very. reasonable cost, and

while the foregoing description has been in specific terms, it is to be understood that changes within the scope of the appended claim, may be resorted to in the manufacture of the mechanism. I A

Having thus described my invention, what I claim as new is In combination with a motor vehicle in- :cluding a steering column, the steering wheel at the upper end of the column-and the throtjtle valve, a sectional sleeve movably arranged 'on the rimof the wheel for rotary move- 35 ment, a shaft extending through the upper end of the column, an arm connected at the center to the upper end of the shaft, a pair of oppositely arranged cams on the hub of the wheel for engagement by. the ends of the arm when the arm is moved from a neuitralposition between the cams, links having their inner ends connected to the ends of V the arm and passing through some of the spokes of the wheel and having their outer ends conn ected with parts of the sleeve, and

means for connecting the lower endof the V I shaft to the throttle valve.

' In testimonywhereof I aflix my signature. 7
